    This is an absolute must watch for anyone interested in future technology and energy.

    It's a film which shows people who devote their lives to grand bold projects for idealistic reasons. It also examines the obstacles such projects face.

    The film explains what fusion is and what it could become if people manage to harness it. It does so through the words of scientists working on it. And one can see how hard it's for them to explain. Therein the problem lies. Fusion should be publicly understood and supported. But for some it seems to reside in the realm of science fiction and that's the best case scenario. For many it's not something they concern themselves at all.

    Let there be light talk about something very complicated and presents it as a very human thing. There is the best of humanity and reason in this film. Still much of it is shrouded in human pettiness and bureaucratic nightmares.

    Really solid documentary about fusion energy research. Technical enough to be interesting, broad enough to be accessible. Really interesting study on how politics and research intersect. I dug it.
